Product Description
Harmonic Drive, mechanical speed-changing device, invented in the 1950s, that reduces the gear ratio of a rotary machine to increase torque. It operates on a principle different from that of conventional speed changers. The device consists of a thin ring that deflects elastically as it rolls inside a slightly larger rigid circular ring.
There are three elements in a basic Harmonic Drive: a circular spline, a flexspline, and a wave generator. The circular spline has internal teeth that mesh with external teeth on the flexspline. The flexspline has fewer teeth and consequently a smaller effective diameter than the circular spline. The wave generator is elliptical in shape and acts as a link with two rollers that rotates within the flexspline, causing it to mesh with the circular spline progressively at diametrically opposite points. If the wave generator (the input) rotates clockwise while the circular spline is fixed, the flexspline (the output) will rotate or roll inside the circular spline at a much slower rate in a counterclockwise direction.

Key Features
Ultra-flat harmonic gear reducers are highly suitable for use as robot end joints and customer-end reducers.
These new high-torque, zero-backlash gear units have an ultra-flat configuration and feature a large cross-roller bearing with high-moment stiffness.

FAQ
1. Can a harmonic drive be backdriven?
Yes the harmonic drive gear can be driven back. By the way, this happens in every typical robotic cycle hundreds of times every day: Every time when the axis is in motion and slowed down rapidly, the load inertia on the gear output side drives back the gear (in a controlled manner, determined by motor and controller).
2. What does a harmonic drive do?
Hamornic drives are used in increasing the output torque in gears used in milling, in manufacturing, and in machines that use robotic arms.
Yes of course. We can customize a harmonic drive based on customer's specific requirements and drawing.
4. What's the biggest advantage of your products?
We can provide complete product series, and the qualty of our harmonic drive is stable. The most important is the highest cost-effective in China.
5. What are the main components of a harmonic drive?
